Advanced magnet systems for fusion applications would greatly benefit from the use of high-temperature superconductors (HTS). These materials allow fusion magnets to operate at higher magnetic fields, allowing for more compact fusion machines, and allow for operation at elevated temperatures, enabling demountable coils that provide access for maintenance of the fusion reactor. Quench detection remains a major challenge in the protection of HTS magnets that are vulnerable to localized conductor burnout due to their low quench propagation velocities. One of the methods explored is the use of Hall sensors that are incorporated in or near the magnet terminations that can detect local field variations that occur as a result of current redistribution within the conductor to bypass a hotspot within the magnet winding. This method is potentially well suited for Cable in Conduit Conductors, such as those made from Conductor on Round Core (CORC) cables, in which sub-cables containing HTS ...

在基于高温超导CORC®的导管中电缆中使用霍尔传感器进行骤冷检测，以进行融合应用

用于熔融应用的先进磁体系统将大大受益于高温超导体（HTS）的使用。这些材料允许聚变磁体在更高的磁场下运行，从而使聚变机器更紧凑，并允许在高温下运行，从而实现可拆卸的线圈，从而为聚变反应堆的维护提供方便。淬火检测仍然是保护HTS磁体的主要挑战，由于其低的淬灭传播速度，它们容易受到局部导体烧毁的影响。探索的方法之一是使用霍尔传感器，该传感器集成在磁体终端中或磁体终端附近，可以检测由于导体内电流重新分布而产生的局部磁场变化，从而绕过磁体绕组内的热点。
